If you boot with a -current kernel:
(da0:ahc0:0:0:0) data overrun detected in Data-In phase. Tag = 0x8
(da0:ahc0:0:0:0) Have seen Data Phase. Length = 0, NumSGs = 1
Backing out the following sys/cam/scsi change set:
revision 1.39
date: 1999/10/01 09:34:09; author: phk; state: Exp; lines: +47 -117
Introduce the disk mini-layer and devstat_end_transaction_buf() in cam/scsi.
..and the other files touched at the same time revived it and made the
system bootable again.
I am particularly suspicious about this:

- softc->flags |= DA_FLAG_OPEN;
- }
+ if (cam_periph_acquire(periph) != CAM_REQ_CMP)
+ return(ENXIO);
+ softc->flags |= DA_FLAG_OPEN;
At first glance, it would appear it's re-inquiring on each open instead of
the first open, including while it's mounted. I wasn't sure, so rather than
risk disks, I backed the lot out and it worked again.
